Description

The uncertainty of top pair production cross section measurement at LHC is at a few percent level, which still allows the stop pair production with identical final states 2b+l+nj+$E_T$. On the other hand, the prompt decay of top quark before hadronization provides opportunity to make its precision measurement possible. In this talk, we apply the ATLAS $χ^2$ method of W-polarization measurement in semileptonic top pair events to semileptonic stop pair events and study its prediction. We attempt to use the existing measurement of W-polarization in top quark decay to improve the distinction between stop and top quark states.
